This book gives a comprehensive survey of the structure and fiber connections of the brain stem in a well-differentiated lizard, the savanna monitor lizard, Varanus exanthematicus. It comprises a cytoarchitectonic analysis of the cell masses in the brain stem, a discussion of the localization of monoaminergic and certain peptidergic neuron systems and a review of the experimental data currently available on this lizard and on closely related species. The structure of the brain stem is discussed in terms of functional systems; wherever possible, the cell masses are treated in the framework of their interconnecting fiber paths as demonstrated by tract-tracing techniques and in relation to experimental data on other reptiles. Furthermore, some comments on the similarities and differences between the reptilian and the mammalian brain stems are presented. Research in "lower" vertebrates, including reptiles, has added much to our knowledge on basic features in the organization of the neuronal circuitry common to vertebrates.

Monitor lizards (genus Varanus) have attracted a great deal of interest--these large and impressive lizards are often the centerpiece of reptile house exhibits. Monitors tend to be fairly wary and difficult to observe--therefore they are not particularly tractable research subjects, but they have nevertheless received an extraordinary amount of attention from devoted students.Varanoid Lizards of the World is a comprehensive account of virtually everything important that is known about monitor lizards, beginning with detailed species accounts and proceeding to various modern comparative analyses. Where possible, people who have had detailed field experience with a particular species have assembled species accounts. In the process of reporting what is known, we also identify what remains to be learned about these lizards. We hope to establish a prototype showing how such a diverse monophyletic group can be exploited both to identify and to understand the actual course of evolution. As such, this effort becomes a protocol for future workers to follow for other groups of closely-related species.

Handbook of Behavioral State Control: Cellular and Molecular Mechanisms provides the first synthesis of information on the neurobiology of behavioral states, ranging from normal stress and sleep deprivation to debilitating neuropsychiatric disorders. This book presents a working reference on the cellular and molecular mechanisms generating arousal states; pharmacological and non-pharmacological methods of behavioral state control; and the bi-directional interaction between arousal state and the neurobiology of pain, and between sleep and the immune system.

An overview of the fundamental ways that the brainstem influences the initiation, mediation, and regulation of behavior--and the first major survey in the subject since the appearance of the classic work, The Reticular Formation Revisted. Also featured are an introductory tutorial section that synthesizes research discoveries with the historical milestones in brainstem research, basic neuroanatomy, arousal, etc., that are related to behavorial ``readiness,'' sensory and motor functions, and neuroendocrine and autonomic functions. The latter part of the book features a series of specialized topics, each written by a noted authority in the field.

In this book, the structure, function, and development of brain systems using the catecholamines are comprehensively described for members of all living vertebrate classes. The first part of the book deals with comparative morphology and consists of an introductory chapter on methodology and limitations of catecholamine research followed by surveys of the anatomy and function of catecholamine systems for each vertebrate class. These chapters provide information on the distribution of catecholamines and their synthetic enzymes and on their relationships with specific functional systems and other neurotransmitter systems. In the second part of the book, special attention is paid to the first appearance of enzyme- and catecholamine-immunoreactivity in specific brain regions, to the maturation of catecholaminergic cells and fibers, and to relationships with other developmental events. In the final chapter, the morphological and developmental information is synthesized and major evolution implications and basic principles of organization and function are pointed out. The contributors provide an excellent overview of the current knowledge on organization and evolution of the catecholoaminergic systems of the brain and emphasize that brain catecholamine systems are very ancient and appear to be one of the backbones of the brain.

This atlas instills a solid knowledge of anatomy by correlating thin-section brain anatomy with corresponding clinical magnetic resonance images in axial, coronal, and sagittal planes. The authors correlate advanced neuromelanin imaging, susceptibility-weighted imaging, and diffusion tensor tractography with clinical 3 and 4 T MRI. Each brain stem region is then analyzed with 9.4 T MRI to show the anatomy of the medulla, pons, midbrain, and portions of the diencephalonin with an in-plane resolution comparable to myelin- and Nissl-stained light microscopy. The book’s carefully organized diagrams and images teach with a minimum of text.
